To all whom it may concern: Be it known tl'ist l, FRANK Bronson, a (Hillzen of the United States, residing at 'Dolge Ville, in the county of .Los Angeles mid State of California, have invented new and weird 1m rovements in Bum -Csrs of which the l 7 following is s sieo liootion.

AllObJGOt of this invostion 2"- lo so con struct a dump cor that in the psrstion of dumping the some ov tilting; the oody of the car the lovvsr end of a door that sido or can be dumped. That is to say, by this invention the car-floor and the lower end of the door simultaneously reoedo soul). from other during the tilting motion given to the car body- Strength, simolicity and free action oi the arts are'elso ohjeots in view.

'- Anothor object is to hold the door rigidly in whatever position it assumes, and to prevent the. some from flopping or swinging loosely at any time.

Anothor object is to provide positive means for holdim the door shut whenever the car is in upright position, and to mskc it impossible for any opening to occur at the door except when the car is tilted.

Another object is to avoid on pressure or frictional resistance of the load on the door during the operation of dunn'iins The accompanying drawings illustrate the invention.

Figure 1 is s side elevation of the dnnr; car with. parts in position for carrying a load. Dotted lines indicate the tilted or dumping position. Fig. 2 is a perspective side View of the same car in the set of dumping. Fig. 3 is a ers ective view of said oar rrom the same side 0 the carriage, showin the body of the car tilted to dump sidewise i rom the osrringe.

Fig. 4 is a plzm of the car.

1 desi nates the carriage of the ear, and 2 a turnta hle pivoted thereto st 8. These severol parts may be of the usual construction.

4 is the car body which moy be oi any opproved form of construction, and is liingod or pivoted to the front end of the turntable, as shown at 5. In the formshown, the our body is a. rectangular sheet-mists: box. the

floor, two sides, and one end will of which are fixed rigidly to each other. .The top and one end of said box are open.

6 is a door for closing t S, at the upper and lower ends terminating pivots i end it) on each sids of the door.

The turntable Z the carriage is provided with a. door-support oomprisins two station my forwardly-slenting stsudords i i 2, suit ported by struts 13 and projecting upwardly and forwardly from tho turntable 2. The upoor door )ivots 9 are pivoted to the ends of said standards.

Ll designates two rigid links itoted re spectively to the box or our ho y walls by pivots 15 ot the 11 per corner thereof, at the closed end of the ox, and by the pivots 1G to the lower end of; the door 6. lire space between the pivots 15 and 10 of the links 14 is mproxinmtely equal to the diagonal of the ox side horn the upper rear corner to the lower front corner.

16 is o. brace connecting the 11 per corners of the side WitllS at tho open on of tho box .to hold the some in true position.

17 designates s rings to resilien'tl support the closed on of the box when t e box is in losd-holding position. Said sprin s may be bent up from the straps 18 that hoid tho pivot 5 on the turntable.

19 designstes the usual s ring-messed lot :21 to engage a keeper 2O w iien the rear end of the box is down.

21 designates a. foot-piece for retracting the spring-pressed latch 19 to release the box- 22 designates the'dsuol handle for tilting the box.

When the box is in the lcmd-csrrying posi tion shown in Fig. i, it rests u )011 the turd table of the carriage, and the oor 6 is held by the links or bars 14in vertical position. in the open end of the box.

Whenever it is desired to dump the load. the closed and of the box may be lifted to tin, the box on its :L7 (l8 or pivot a. As the box is thus tilted, the open end thereof oorrcspondingly lowers sway from the upper door pivots 9, and at the some time the rear pivots T5 move upward and forward, thereby pushin forward and upward the lower end of the door 6 at the some time thot'the open end of the box moves downward and bookward. By this reverse movement of these two parts upper the opening at the front end of re open end of the. box. The some 15 provided with brackets 7,

the box is rapidly widened to allow the load I to pass through.

it is to be uderstood that the invention is f not limited to a construction in whielpthe pivot for the box is carried by a turntable, l or that the turntable is a part of the invention. I

By pivoting the. box and the door to relai tively stationary supports and connecting the box and the door by link means that tend to swing the door open as the box tilts, the load .is practically prevented from i'rietionally contacting with the door in the act i of dumping.

I claim:

1. 1L dump car provided with standards, a box open at one end and pivoted to tilt relatively to said standards, a door pivoted to said standards and adapted to close the open end of the box when said box is un tilted, and links pivoted to the doorlgelow its supporting pivots and pivoted to tlie box, at the upper rear portion thereof.

2. The combination witlr a carriage, of a box pivoted thereto, standards on the ear riage, a door for the'fbox pivoted to the standards, and nieans connecting the door and the box to lDOVGtllG' door on its pivots as the box moves on its pivot.

A carriage provided with standards, a box pivoted to the carriage and provided with an open end between said standards, a j

i l l l l l l l I door pivoted to said standards and arranged in the open end, and links pivoted to the box and to the door to swing said door forward and upward whenever the floor of the box tilts forward and backward.

4-. The combination with a carriage, of a.

and adapted to close said open end of thebox when the box is upright, and rigidlink means pivoted to the oox and to the door to hold. the door elosed when the box is upright and to open the'door when the. box is tilted.

- 6. A turntable, a box thereon pivoted to tilt, a door for the box pivotally connected with the turntable, and means connecting the dobr and the box to automatically swing the door as the box tilts.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this- 30th day of November, 1907.
